The big news to me is that the top card features a 320 bit memory bus, which should offer much better memory bandwidth than the previous generation (256 bits). Assuming a linear scaling, we should see a 1.25 improvement compared to the previous generation.

RTX 2080 is 352 bits, and RTX Titan is 384. Nvidia has always had high bit rate memory bus. The one that had 256 bit was AMD Radeon GDDR. Arguably bit bandwidth is meaningless without looking at actual memory type, or the total bandwidth from memory.

Indeed, seeing that there's also Radeons with 2048 bit bus for HBM.

Actually the RTX 2080 has only 256bit. https://www.techpowerup.com/gpu-specs/geforce-rtx-2080.c3224

The 2080 ti has 352bit. https://www.techpowerup.com/gpu-specs/geforce-rtx-2080-ti.c3...

Interestingly, Nvidia decided to use a bigger die (relative to other dies in the family) for the 3080 than for the 2080. TU104 (2080) vs GA103 (3080). Probably to prepare for big Navi.

Any word on what the 3080ti will have?
